Myth 1: Mammary gland hyperplasia can be cured by long-term oral medication Mammary gland hyperplasia is a group of diseases or disease processes that are chronic and related to endocrine disorders. The lumps and pain of hyperplasia can be treated with medication. However, mastocytosis is also a psychogenic disease, which can be caused by many psychological disorders such as anxiety and depression. If the psychological effects are not removed, medication alone is useless. Myth 2: Mammary gland hyperplasia will not turn into cancer Overall, mammary gland hyperplasia is a benign disease and patients should not be too nervous, but they should not rest on their laurels. If the cause of mammary gland hyperplasia is not removed, the long-term stimulation of breast ducts and mammary epithelium may cause atypical hyperplasia, which may lead to the occurrence of breast cancer. Therefore, mastopexy needs to be followed up in hospital. In fact, puncture biopsy is a fast, convenient and accurate method to determine the nature of the disease and will not cause metastasis or malignant transformation of benign tumors. A survey of 100,000 cases in the UK did not find a single case of malignancy or metastasis caused by puncture biopsy. Besides, once the nature of the disease is quickly determined, especially the tumor, its subsequent treatment (surgery, radiotherapy, chemotherapy) also gives the tumor no respite and brings survival benefits to the patient; on the contrary, not timely diagnosis, not understanding the nature of the disease and untimely treatment will lead to metastasis and recurrence of the tumor. Myth 4: The more mammograms the better Mammograms are the best way to detect early breast cancer, but it is unnecessary to have repeated examinations within a short period of time, especially the breast during adolescence and pregnancy and lactation are sensitive to X-rays, and over-exposure will increase the incidence of breast cancer, which is worth noting. once a year examination is usually enough for those above 40 years old. Myth 5: Breast enlargement cannot be cured, but will naturally get better after having children or menopause Expert opinion: Recurring breast enlargement is due to incomplete treatment, insufficient medication courses, and stopping medication when breast pain gets better, so that the treatment of enlargement is delayed. During pregnancy, breast enlargement increases, hormone levels increase, and breast enlargement is exacerbated, and after weaning, we have to go through a process of hormone level changes, which is a stimulus for breast lobules and ducts. Therefore, it is completely wrong to say that mastocytosis will heal after having a child. Myth 6: Mammary gland hyperplasia does not need to be treated and can be completely self-healed Expert opinion: There is a process of malignant transformation of normal breast epithelium, i.e. hyperplasia – atypical hyperplasia (precancerous lesions) – carcinoma in situ – infiltrative carcinoma. Breast diseases are divided into benign, junctional and malignant diseases. Benign ones include hyperplasia, fibroids, cysts, lipomas, papillomas, etc.; junctional ones are lobulated cystic sarcoma; malignant ones are lymphoma, breast cancer, breast metastatic cancer, etc. If hyperplasia is left to its own devices, benign diseases can also become malignant. In addition, environmental pollution, food additives, late marriage and childbirth, mental tension, stress and other factors have contributed to the high incidence of breast disease.
